AO3401A

The AO3401A is a P-Channel Enhancement Mode Field-Effect Transistor (FET) manufactured by UMW (Youtai Semiconductor Co., Ltd.). This transistor is designed for use in various power management and switching applications where low voltage drop and high efficiency are required.

Key Features:

• P-Channel MOSFET: The AO3401A is a P-channel MOSFET, which means it conducts current when a negative voltage is applied to its gate terminal relative to its source terminal.

• Enhancement Mode: It operates in enhancement mode, meaning it is normally off and requires a positive voltage at the gate terminal to turn on the transistor.

• Low On-Resistance: The transistor has a low on-resistance (RDS(on)), which results in minimal voltage drop across the transistor when it is conducting, leading to high efficiency and reduced power dissipation.

• Fast Switching Speed: The AO3401A features fast switching speeds, enabling rapid switching between on and off states, which is essential for applications requiring high-frequency switching.

• Compact SOT23 Package: Packaged in a small SOT23 surface-mount package, the AO3401A offers space-saving benefits and is suitable for use in compact electronic devices and circuit designs.

• Wide Voltage Range: Capable of handling a wide range of input voltages, making it versatile for use in various voltage regulation and power management applications.

• RoHS Compliance: Manufactured in compliance with the Restriction of Hazardous Substances (RoHS) directive, ensuring environmental sustainability and compatibility with lead-free soldering processes.

Applications:

• Battery protection circuits
• Power management in portable devices
• Load switching in DC-DC converters
• Voltage regulation circuits
• Motor control circuits
• LED lighting drivers
• Switching regulators
